sncrrrcArroN foi-ming part f Letters Patent No. 650,239, dated May 22, 1900. Application filed December 27, 1899- Serial No. 741,751. (No model.)

To all whom it may concern:

Be it known that I, NARCISSE ALEXANDRE GUILLAUME, a citizen of France, 'residing at 15 Rue du Louvre, Paris, France, have ina Vented certain new and useful Improvements in Apparatus for Washing Gas, of which the following is a speciiication.

This invention 1s more especially applicable to apparatus workin g under suction. he

gas entersin the form of a thin sheet in prox-Q understood, I will describe the same with reference to the accompanying drawings, in which Figure lis a longitudinal section of my apparatus. Fig. 2 is a transverse section thereof, part on the line A B C D E F and part on the line Gr H of Fig. l. Fig. 3 is a horizontal section thereof on line M N of Fig. l.

The apparatus, as shown, is constructed of a series of superposed rectangular troughs a, fitting into each other by ribs on the one engaging with grooves on the other and secured together by means of vertical bolts b or otherwise by joints giving a sufficiently-tight closure. The lowermost trough c is mounted on columns d, supporting the apparatus, and eX- tending up through each trough at the corners thereof and also down into the columns are threaded rods e, the movement of which l is controlled by bevel-wheels f and pulley g at the top h of the apparatus.AV By means of this device the several troughs can be lifted or lowered, so as to secure a uniform tightening of the joints.

Each trough a is divided by a partition t' into two compartments, the one of which, j, is small, these small compartments when the troughs are superposed constituting a vertical conduit for the outlet of the washed gases and the larger compartments constituting the troughs in which the washing takes place. The troughs have each a splayed tube 7c, passting through the bottom of the said trough,

for water may be controlled by a oat.

and a cup m, both being so arranged that the lowerV end of the tube la is immersed inthe water contained in the cup lml of the trough beneath. A The gas enters each washing-trough by several lo'ng and narrow openings 'n at bottom, Fig. 3, with sides o rising into the trough, and over these hoods p are placed, which hoods have serrated lower edges and are supported at their ends, so that serrations dip into the water in the troughs and offera gradual increase of the area for the passage of the as when the water-level in the hoods fall.

`The lowermost trough is provided with a tubularentrance-conduit r for the gas, the said conduit extending into the lowest trough c and being attened out`toward its end, so that the gas passes from this conduit in the form of a horizontal sheet to meet the water 7o which has served for washing the gas and which overiiows in a thin sheet from a box t,

situated before the incoming stream of gas. f*

The said lowermost trough has a sloping bottom c, and the washing-water passes off at the lowest part through an outlet u, provided with a iioat-valve c. Vhen the suction by which the gas is drawn in becomes too strong, the iloatvalve fo closes. Gas leaves the apparatus by a conduit no, which is placed at the lower part of channel. The water enters through a pipe/y inwx the upper trough, this pipe being flexible in order not to loosen the joint, and the entranIcc n each compartment the water rises till it overflows the splayed tube lc aforesaid, and it flows through this tube into the cup, in beneath which it overiiows and passes into the next trough, and so flows down from trough to trough till it overiows the boX in the lowermost trough in front of the incoming gas, l

as aforesaid, which gas impinges against this water and then passes through the openings in the trough and under the hood and between the serrations and through the water that surrounds the hood and which retains the impurities contained in the gas. The gas thus successively passes through the water in each trough and then descends in a washed condition through the vertical conduit formed by the aforesaid smaller compartments j, constituting the gas-outlet, leaving the apparatus at fc, formed in the lowermost trough c.

xo surrounded by` an 'endless vertical wall,- Va- *3o wheels upon the Having vnow particularly described and as.- certained the nature of this'in'ventionand ini what manner the same is to be performed, Il declare that what I claim is 5-v 1. In an apparatus for washing gas,- the combination with a series of superposed troughs eaclrhaving. longitudinal openings in`Y its bottom forming communicating passages v between the troughs and each passage being dome or pan seated over and inclosing each,4 passage, water-overflow pipes or passages comm unicatin'g 'with Y the4 several trou.,g,hs',-` af Water-tank arranged in the lowerm-ost trou-gh b and located below the water-passage in the,`

trough above it, the water overlowingfrom/ said-tankin a thinsheet, and a gas-inlet pipe Opening' ,into said lowe'rmosh trough and hav-1 ing its" discharge end located adjacent to the 2o said water-tanksp that the in'fiowing gas will bedisc'lrarged inltodi'rectoontact .with the sheet of vwater overiowing from` the'y tank, substantially as described.

Q.In an apparatus for washing gas, the

combination-with a;V plurality lof sl'lperposed troughs forming a closed column with communicating passages between the troughs, threadedrods passing through saidv troughs I and in threaded engagement therewith, gearupper ends of said rods, and corresponding gears meshingwith the gears onthe rods to operate the latter, snbstantiallylas and for thepurpose specified. 3. Inf-anl apparatus for washing gas, the 35 combination Vwith a series .of su perposed ..stidcompartments .troughs are in posi ing from within th 4 charging y-into an outlet-pipein the'bottom trough, a water-tank arranged in Vthel'owermost trough below the waterfpipe, the water overflowing from said and a gas-inlet pipe opening into thelowen. most trough in position ing gas" into direct contact with the-overliowing sheet of waterv from substantially as described'.

om'partm'ent'inv each trough, said compartments communicating when the troughs are in position, to provide a gas-outlet passage, nd a gas-inlet pipe leading into the lowermost trough', substantially as' described.

4. In an apparatus folwashing gas, the 00mbinatiofn .troughs forming aA closed colum min iicating` 'iow of gas, i "eachtroughl communicating with the trough with aser-ies of superposed n with comand a Water-overflow pipe in glow, anend compartment 1n each trough, communicating when the tion one upon .theother to lgas-outlet passage leade' ltop trough. and s. disVd rovide a continuous tank in sheet form,

to direct thein'low the aforesaid.tan-vk,

In testimony whereof I havehereuntoset my hand in presence of two subscribing.Wi-t-l nesses.
